Key legal question
Whether the bank retained its rights against the co-caution under Art. 303 LP after adhering to the concordat.
Extracted holding
Yes. By asking the co-caution for instructions and then adhering in accordance with his communicated will, the bank preserved its claims.
Extracted reasoning
Art. 303 al. 3 LP allows the creditor to preserve rights if it consults the co-obligor and acts according to the latter's decision. The co-caution's reply, interpreted in good faith, covered the disputed claim and instructed adhesion to the concordat.
